Egerton has said that the film will not be your typical biopic. Speaking with Collider, he said, “Everyone thinks it’s a biopic. It isn’t. It’s a fantasy musical so it’s actually his songs used to express important beats in his life at emotional moments." He added, "He’s not the only character that sings. It’s going to be fun.”

Elton John appeared onscreen with Egerton in 2017's Kingsman: The Golden Circle.

The first trailer for the film is slated to be released next week.

Initial prospects to play Elton John before Egerton was cast included Justin Timberlake and Tom Hardy.
